Abstract
A cleaning composition according to one embodiment includes a surfactant system comprising nonionic surfactant in combination with an anionic surfactant; water present in an amount from 0 to about 40 wt % based on a total weight of the cleaning composition; a solvent system comprising a polyalcohol, the solvent system being present in an amount effective to solubilize the surfactant system in the water; and an enzyme present in an amount of less than about 15 wt %; wherein the cleaning composition is in a form of a continuous phase, wherein the cleaning composition is characterized as exhibiting about a constant cleaning efficacy as measured using test procedure ASTM D4265 when the cleaning composition is added to 69 liters of exterior water in amounts ranging from about 9 to about 22 grams of cleaning composition. Methods for pretreating and cleaning laundry and nontextile surfaces are also presented.
